SWING-TENT.

SPECIFICATION forming part of Letters Patent No. 425,540, dated April15, 1890. Application filed October 9, 1889. fierial No. 326,403. (Nomodel.)

T0 or whom it may concern.-

Be it known that I, BRUNO FORBRIGER, of Schonefeld, near Leipsic, in theKingdom of Saxony, Germany, have invented a new and useful Swing-Tent,of which the following is a specification.

This invention is illustrated in Figures 1 to view of the rests or stopsf f and adjacent parts; Fig. 10, a sectional side view of one of theturning spindles; Fig. 11, elevation of coupling for the middle upperyoke; Fig. 12, a transverse section,and Fig. 13 a plan, of the same.Fig. 14 represents the fastening for tent-cover with middle yoke insectional end View, and Fig. 15 the same in plan.

The above-illustrated invention is for a folding tent-frame which can beused in place of life-saving baskets and many other purposes. Thistent-fram e, owing to its folding and rocking nature,is constructed in apeculiarmanner. It consists, principally, of a series of open bentsections or yokes preferably arched which attain their purpose in diversmanners,

and the particular construction is illustrated in the drawings and thefollowing description.

The tent-frame is shown in position for use in Figs. 1, 2, and 3, andinafolded position in Figs. t to '7, while Figs. 8 to 12 show variousdetails of construction.

The arched sections or yokcs A and B of the tent-frame serve to supportthe whole structure. They rest upon the ground and are braced from eachother by means of the foldingbrace K. Th e arched sections or yokes Aand B are also rockers and serve for rocking the tent.

The arched sections or yokes E F serve for holding the tent cover, andthe adjacent arched sections or yokes (J D,forming the up per part orroot of the tent, (see Figs. 11 to 15,)

are held together by means of a peculiar coupling consisting of a claspG or a spring.

All of the arched sections or yokes are pivoted and turn upon thespindles a. at their ends, and the ends of these spindles are soconstructed (for example, with loops or eyes, as shown) as to allow ahammock to be swung upon them. (See Fig. 1.) All the sections or yokesare jointed in the middle by joint I), so that they can be folded so asto resemble a quadrant. (See Fig. 6.) The spindles a a are provided withthe rests off (see Figs. 8 to 10) for the purpose of supporting thesections or yokes E F, and by means of which, when the tent is erected,the sections or yokes E F are in a sttte of tension with respect to CD.(See Fig. 2.

The folding of the tent-frame is as follows: The upper sections or yokesC D are separated and the jointed braces K are folded. The cover istaken off and rolled up. The frames A B O D E F lie close together, oneabove the other, as shown in Fig. 4, forming a semicircle, and by meansof the joint 0 they may be folded in the form shown in Fig. 6. In thismanner the tent can be folded i'naverysmall compass and is readilyportable, and has the advantage that the body of the person resting canreceive not alone the rocking motion from the hammock, but from thewhole tent, which will generallybe done mechanically by the action ofthe wind, especially when the outer surface of the tent isproperlyturned to the Wind. This arrangement of tent is superior to theordinaryones, not alone on account of the superior comfort afiorded, butalso in the practical nature of the construction.

I claim- 1. Atent-frame composed of a series of yokes, in combinationwith spindles to which they are pivoted at their ends, all substantiallyas described.

2. A tent-frame consisting of a series of arched sections jointedsubstantially in the middle, in combination with and pivoted at theirends on two spindles, whereby the tentframe may be folded up intoquadrant shape, all substantially as described.

3. A tent-frame consisting of a series of open bent sections or yokes,in combination with and connected at their ends to spindles, saidspindles being provided with loops for attaching a hammock, allsubstantially as described.

I0 ff, the yokes A and B being connected by the jointed braces K K, allsubstantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

BRUNO FORBRIGER.
